The electronic device 80 may include an Internet protocol television (IPTV), a personal computer (PC), a personal digital assistant (PDA), and a smart phone.

Hereinafter, operation of the navigation system according to a first exemplary embodiment of the present invention will be described in detail.

FIG. 4 is a flowchart illustrating operation of a data server according to a first exemplary embodiment of the present invention, FIG. 5 is a flowchart illustrating operation of an electronic device according to a first exemplary embodiment of the present invention, and FIG. 6 is a flowchart illustrating operation of a navigation device according to a first exemplary embodiment of the present invention.

Hereinafter, for convenience of description, it is assumed that the electronic device is an IPTV and the network 30 is Internet. Further, it is described as the video output unit 310 includes a display device.

Referring to FIGS. 4 and 5, operation of the IPTV 80 and the data server 70 will be first described. The IPTV 80 is connected to the data server 70 according to a user request (S102). The IPTV 80 is connected to the data server 70 through an Internet web browser. The IPTV 80 transmits first identification information to the data server 70 (S104). Accordingly, the data server 70 receives the first identification information (S106). The first identification information may be a user ID for connecting to the data server 70, or may be an intrinsic identification number given to the IPTV 80.

In order to receive the user ID, the user can input a user description and identification information such as a social security number necessary for the data server 70. In this case, the user can input/register together second identification information of the mainly using navigation device 10. The second identification information may be a serial number of the navigation device 10 or an identification number given to the network communication unit 120. The first identification information may be used for authentication of the user or the electronic device.

The IPTV 80 provides a user interface such as a graphical user interface (GUI) that can receive an input of user input information (S108). Thereafter, the IPTV 80 receives an input of the user input information using the GUI (S110). The user input information may be input by the user input device 83. The user input information may include a starting point, a destination point, a passing point, and an essential passing segment.

The GUI may be provided by a navigation application for appropriately receiving an input of the user input information necessary for forming path setting information according to the present invention from the user. The navigation application is provided by the data server 70 and is driven on Web. Alternatively, the navigation application is stored at the IPTV 80 and may be driven in the IPTV 80. The navigation application provides the GUI and includes path search algorithm that searches for a path based on the user input information.

Thereafter, the IPTV 80 transmits the user input information to the data server 70 (S112).

The data server 70 receives the user input information (S114). The data server 70 acquires a moving path (hereinafter, moving path information) from the starting point to the destination point based on the user input information (S116). In order to acquire the moving path information, the data server 70 can use various path search algorithm. For example, as described above, various path search algorithm according to a search condition such as a shortest path, an optimal path, and a shortest time path may be used for acquiring the moving path information. In this case, the user can select algorithm to search for a path. Alternatively, the user may select one of a plurality of moving paths acquired using a plurality of algorithm. The moving path information may be acquired from the IPTV 80 according to a case.

Hereinafter, reception of an input of the user input information will be described.

FIGS. 7 to 10 are diagrams illustrating screens that receive user input information according to a first exemplary embodiment of the present invention.

The user can input a starting point, a destination point, and a passing point. Accordingly, the data server 70 or the IPTV 80 acquires a preliminary moving path PR according to the input information and displays the preliminary moving path PR together with a map image in the display device 82 of the IPTV 80. When the user has a segment wishing to essentially pass (hereinafter, an essential passing segment) unlike the preliminary moving path PR, the user can input an essential passing segment R1 through the user input device 83. As shown in FIG. 9, in order to set the essential passing segment R1, the user can use a method of directly changing some segment of the preliminary moving path PR through an input device such as a touch screen or a mouse in order to pass through other segments. Alternatively, as shown in FIG. 10, the user may set the essential passing segment R1 by inputting a road name of the essential passing segment. In addition, various user interfaces for receiving an input of the essential passing segment R1 may be provided.

The user input information may include additional interest information. The additional interest information may be information about good taste restaurants, information about historical archaeological sites, and information specially interested and registered by the user. The additional interest information may be information normally specified and stored by the user as additional interest information, and may be information separately input while inputting the user input information. The additional interest information may include a position coordinate of a corresponding region and various information of the corresponding region. For example, after a user reads an article about ‘Mongchontoseong’ the user may register the article as additional interest information. Alternatively, the additional interest information may be selected from information provided from the data server 70. For example, the data server 70 provides information about various recommended tourist sites, good taste restaurants, and historical archaeological sites at a periphery of a moving path acquired by the user input information, and the additional interest information may be information selected from the above information by the user. The additional interest information may be appropriately provided to the user through the navigation device 10. This will be described later.

Although not shown in the drawings, the navigation application may provide trial driving information. For example, the navigation application may provide simulation drive like actual driving according to the preliminary moving path PR or the acquired moving path information. Accordingly, the user can add or adjust the user input information.

Referring again to FIGS. 4 and 5, when the user input information is received (S114) and the moving path information is acquired (S116), the data server 70 generates path setting information based on the user input information and the acquired moving path information (S118). The data server 70 generates title information corresponding to the path setting information together with the path setting information (S118).

The path setting information includes a destination point input by the user input information. The path setting information may further include at least one of the passing point, the essential passing segment information, and the acquired moving path information. Further, the path setting information may further include the additional interest information.

The title information may be generated by the data server 70 based on the destination point and the passing point. For example, when it is input as the destination point is ‘A’?and the passing point is ‘B’, the title information may be generated like a ‘path for the destination point A via the passing point B’. Further, the title information may be generated to reflect a date and time point in which the user input information is input to the title information. The title information may be generated by other various methods. Alternatively, the title information is the user input information and may be directly input by the user through the IPTV 80.

The data server 70 stores the generated path setting information and the title information (S120). The path setting information and the title information may be matched to the first identification information and be stored.

Hereinafter, operation of the navigation device 10 and the data server 70 will be described with reference to FIGS. 4, 6, and 11.

FIG. 11 is a diagram illustrating operation of a navigation device for receiving path setting information according to a first exemplary embodiment of the present invention.

Referring to FIGS. 4 and 6, the navigation device 10 is turned on according to a predetermined signal (S122). When the navigation device 10 is turned on, the navigation device 10 is connected to the Internet 30 (S124), as described with reference to FIG. 1. A connection of the navigation device 10 to the Internet 30 may be performed by a user request or may be automatically performed by interlocking with the turn-on operation. For example, as shown in FIG. 11A, the navigation device 10 displays an initial screen together with a turn-on operation, and as shown in FIG. 11B, the navigation device 10 is connected to the Internet 30 by interlocking with the turn-on operation and displays a standby screen for transmitting and receiving various necessary data to and from the data server 70, as described later. The navigation device 10 is connected to the data server 70 through the Internet 30 (S126).

The navigation device 10 requests path setting information to the data server 70.

A request for the path setting information may be performed by the following series of operations.

First, the navigation device 10 transmits second identification information related to the navigation device 10 to the data server 70 (S128). The second identification information may be an intrinsic identification number (e.g., serial number of the navigation device) of the navigation device 10 and may be an intrinsic identification number related to the network communication unit 120 of the navigation device. Alternatively, the second identification information may be an intrinsic identification number given to the storage unit 400 of the navigation device 10. Alternatively, the second identification information may be intrinsic identification information given to the user, which is previously stored at the navigation device 10. The second identification information may be used for authenticating the user or the navigation device 10.

Thereafter, the navigation device 10 requests transmission of the number of path setting information matching to the second identification information and title information corresponding thereto (S130). The data server 70 receives the request (S132), and the data server 70 searches for path setting information corresponding to the second identification information (S134).

In this case, in order to search for path setting information matching to the second identification information, the data server 70 searches for the first identification information corresponding to the second identification information. A search of the first identification information corresponding to the second identification information can be performed based on the second identification information registered when registering a user ID, as described above. Alternatively, a search of the first identification information corresponding to the second identification information may be performed by searching for registered user information of the navigation device 10 by the second identification information and searching for first identification information corresponding to the user information among the first identification information. For example, identification information given to the network communication unit 120 may include information about a user of the network communication unit 120, and the data server 70 may search for the first identification information matching thereto using information about the user.

The data server 70 transmits the found path setting information and title information corresponding to the found path setting information to the navigation device 10 according to the search result (S136). In this case, the data server 70 may transmit the number of the path setting information together with the found path setting information and the title information. The data server 70 may transmit the number of the found path setting information and/or title information according to a request of the navigation device 10, as described above, but may transmit the found path setting information itself to the navigation device 10.

The navigation device 10 receives the title information and/or the number of the found path setting information (S138) and determines whether the number of the found path setting information is plural (S140).

If the number of the found path setting information is plural, the navigation device 10 selects to receive which information of a plurality of path setting information according to a predetermined signal (S142). For example, as shown in FIG. 11C, the navigation device 10 may display the received title information in the display device 310 and thus the user can select path setting information to receive based on the title information. The navigation device 10 may select one of the plurality of path setting information according to predetermined selection algorithm. For example, the navigation device 10 may select most recently generated path setting information. Alternatively, the navigation device 10 may select path setting information generated based on most recently input user input information.

If the path setting information is one, the navigation device 10 determines whether a selection of the user to receive the found path setting information is received (S144), as shown in FIG. 11D. If the user selects not to receive the path setting information, the navigation device 10 is converted to a general path search mode (S146). For example, the navigation device 10 may receive a direct input of the user for a destination point and/or a passing point, search for a guidance path R, and guide the guidance path R to the user.

If a plurality of path setting information is searched for, the navigation device 10 requests to transmit one path setting information selected from the plurality of path setting information to the data server 70, or if one path setting information is searched for and reception of the found path setting information is requested by the user, the navigation device 10 requests to transmit the found one path setting information to the data server 70 (S148). Hereinafter, for convenience of description, both path setting information selected from a plurality of path setting information and one path setting information in which reception is requested is referred to as selected path setting information.

The data server 70 receives the request (S150) and transmits the selected path setting information to the navigation device 10 (S152). The navigation device 10 receives the selected path setting information (S154) and acquires a user moving path based on the received path setting information (S156). The user moving path can be acquired by a predetermined application stored in the navigation device 10.

Step S156 of acquiring the user moving path can be performed by various methods. For example, when the moving path information is included in the path setting information, the navigation device 10 may acquire the user moving path identical to the moving path information. When the passing point is included in the path setting information, the navigation device 10 can acquire the user moving path to surely pass through the passing point. When the essential passing segment is included in the path setting information, the navigation device 10 can acquire the user moving path to surely pass through the essential passing point.

FIG. 12 is a diagram illustrating a navigation device for providing a guidance path according to an exemplary embodiment of the present invention.

Referring to FIG. 12, after the navigation device 10 acquires the user moving path, the navigation device 10 sets the user moving path as the guidance path R and appropriately guides the guidance path R to a destination OP to the user by interlocking with a present position CP received through the position check unit 110.

FIG. 13 is a flowchart illustrating a method in which a navigation device displays additional interest information according to a first exemplary embodiment of the present invention, and FIG. 14 is a diagram illustrating a navigation device for displaying additional interest information according to a first exemplary embodiment of the present invention.

Referring to FIG. 13, when additional interest information is included in the path setting information, the navigation device 10 guides a path (S158), and the navigation device 10 determines whether a distance between a position corresponding to additional interest information and a present position of the navigation device 10 is a predetermined distance D or less (S160), and if a distance between a position corresponding to additional interest information and a present position of the navigation device 10 is a predetermined distance D or less, the navigation device 10 displays various information stored as the additional interest information through the display device 310 (S162). For example, when information about ‘Mongchontoseong’?is registered as the additional interest information and a position of the navigation device 10 exists within a predetermined distance from ‘Mongchontoseong’, various information registered by the user for ‘Mongchontoseong’? may be displayed through the display device 310, as shown in FIG. 14. In this case, a screen of the display device 310 may be partitioned into a path guidance screen and an additional interest information display screen.

The additional interest information may include video, image, and audio information in addition to a text. When the additional interest information includes audio information, the additional interest information may be output through the audio output unit 320.

When transmission/reception of data is complete from the data server 70, the navigation device 10 releases a connection to the Internet 30. For example, after the navigation device 10 receives the path setting information from the data server 70 (S154), a connection of the navigation device 10 to the Internet 30 may be released. Thereby, a cost for transmission/reception of data can be minimized.

Hereinafter, operation of the navigation system according to a second exemplary embodiment of the present invention will be described in detail.

FIG. 15 is a flowchart illustrating operation of a navigation device according to a second exemplary embodiment of the present invention. FIG. 16 is a flowchart illustrating operation of a data server according to a second exemplary embodiment of the present invention. FIG. 17 is a flowchart illustrating operation of an electronic device according to a second exemplary embodiment of the present invention.

Referring to FIG. 15, operation of the navigation device 10 according to a second exemplary embodiment of the present invention will be described.

The navigation device 10 determines whether an actual moving path of the navigation device 10 deviates from a preset guidance path R while guiding the path (S202), and if an actual moving path of the navigation device 10 deviates from a preset guidance path R, the navigation device 10 stores the actual moving path at the storage unit 400 (S204). When storing the actual moving path, the navigation device 10 can store together a separation position and/or a separation time point, which are(is) a position and/or a time point in which the actual moving path deviates from the path. The preset guidance path R may be acquired according to the first exemplary embodiment of the present invention.

The navigation device 10 transmits the stored actual moving path to the data server 70 (S206). In this case, the separation position and/or separation time point may be transmitted together. Hereinafter, the actual moving path, the separation position, and the separation time point are referred to as user actual moving path information. Second identification information, which is identification information related to the navigation device 10 together with the actual moving path information may be transmitted to the data server 70. Further, when the guidance path R is acquired according to the first exemplary embodiment of the present invention, the path may be also transmitted as identification information (e.g., the title information) about some path setting information.

The navigation device 10 transmits the user actual moving path information to the data server according to a predetermined time interval. Alternatively, when a turn-off signal of the navigation device 10 is received, before the navigation device 10 is turned off, the navigation device 10 may transmit the user actual moving path information to the data server 70. Alternatively, when the present position is at a periphery of a destination point, the navigation device 10 may transmit the user actual moving path information to the data server 70. When a connection between the navigation device 10 and the Internet 30 is released, in order to transmit user actual moving path information to the data server 70, the navigation device 10 may be connected to the data server 70 by connecting to the Internet 30.

Although not shown in the drawings, the navigation device 10 may store eco-driving information at the storage unit 500. The eco-driving information is information for determining whether a vehicle in which the navigation device 10 is installed economically drives by a predetermined reference. For example, the eco-driving information may include information about an overspeed/low speed of the vehicle at a predetermined economy speed segment. The eco-driving information may include information about rapid acceleration/rapid retardation of a predetermined economy acceleration. The eco-driving information may be transmitted to the data server 70, similarly to the user actual moving path information, and the data server 70 may store the eco-driving information. In this case, the eco-driving information may be accumulatively stored to correspond to the first identification information or the second identification information. When a request through the IPTV 80 exists, the eco-driving information stored at the data server 70 may be transmitted to the IPTV 80, the IPTV 80 may be provided the eco-driving information to the user. Further, the eco-driving information may be appropriately statistically processed and stored at the data server 70, or the eco-driving information may be formed in a graphic or in a pattern based on the statistically processed eco-driving information and may be stored at the data server 70. The statistically processed or graphically formed eco-driving information or the eco-driving information formed in a pattern may be transmitted to the IPTV 80, and the IPTV 80 can provide the statistically processed or graphically formed eco-driving information or the eco-driving information formed in a pattern to the user.

Referring to FIGS. 16 and 17, operation of the data server 70 and the IPTV 80 according to a second exemplary embodiment of the present invention will be described.

The data server 70 receives the user actual moving path information (S208). The data server 70 stores the user actual moving path information (S210). The user actual moving path information may be stored to correspond to the second identification information and/or the first identification information matching to the second identification information. Alternatively, the user actual moving information may be stored to correspond to identification information of the transmitted path setting information. The data server 70 provides the user actual moving path information to the IPTV 80 according to a predetermined signal (S212).

After the IPTV 80 receives the user actual moving path information (S214), the IPTV 80 displays an actual moving path included in the user actual moving path information in the display device 82 (S216). Step 5214 of receiving the user actual moving path information can be performed by a separate request of the user or by interlocking with a turn-on operation of the IPTV 80. For example, when the IPTV 80 is turned-on, the most recent information corresponding to the first identification information related to the IPTV 80 may be received from the data server 70. Further, as described above, the IPTV 80 may be received the eco-driving information.

Thereafter, the IPTV 80 receives a selection of a use attribute of the user actual moving path from the user (S218). For example, the IPTV 80 may receive a selection from the user about whether to ignore the actual moving path, to use the actual moving path in order to update the moving path information according to the first exemplary embodiment of the present invention, to store the actual moving path as a user intrinsic preference path, or to share the actual moving path with other users. The IPTV 80 transmits an appropriate processing signal of the actual moving path to the data server 70 according to a selection of a use attribute of the actual moving path (S220). The data server 70 appropriately processes the user actual path information according to reception of the processing signal.

For example, when a selection to ignore the actual moving path is received, the IPTV 80 may transmit no signal to the data server 70 or request deletion of the user moving path information. The data server 70 deletes the user actual path information according to the deletion request. When the actual moving path is selected to use for update of the moving path information, the IPTV 80 requests to store the actual moving path to the data server 70. In this case, the data server 70 replaces the moving path information included in the path setting information with the actual moving path according to the request and stores the actual moving path. Accordingly, when the same path setting information is selected later and transmitted to the navigation device 10, the moving path information that may be included in the path setting information is updated to the actual moving path and is transmitted to the navigation device 10.

When it is selected to use the actual moving path as a user intrinsic path, the IPTV 80 transmits an appropriate signal thereof, and the data server 70 can store the actual moving path as a path for a starting point and a destination point used for setting of the guidance path R. Accordingly, when the data server 70 is connected to the IPTV 80 or the navigation device 10, if the starting point and the destination point are input, in order provide the stored actual moving path as the guidance path R, the data server 70 can update path search algorithm provided in the IPTV 80 and/or the navigation device 10.

When it is selected to share the actual moving path with another user, the IPTV 80 transmits an appropriate signal thereof, and the data server 70 can separately store the actual moving path in order to share the actual moving path with other users.

Although not shown in the drawings, the data server 70 can use the user actual moving path information for algorithm for providing an optimal path to the user. For example, the data server 70 may accumulatively store the user actual moving path information and provide an optimal path through statistic calculation of an accumulated separation time point and an accumulated separation position included in the user actual moving path information. That is, at a similar time zone and a similar segment, when the user deviates from a preset path, the data server 70 determines the segment as a traffic jam segment at the time zone. Therefore, when searching for the segment at the time zone, the data server 70 may reflect the information to the algorithm not to pass through the segment, if possible. Further, for the found path of the same starting point and the same destination point, when it is determined that an actual moving segment different from the found path passes through the same segment several times, the segment is determined as a user's preference path and then when the segment is searched for, the algorithm can be updated to search for a path by reflecting the user's preference path.

The updated path search algorithm may be reflected to a navigation application stored at the IPTV 80 and may be reflected to path search algorithm of the navigation device 10.

By the present invention, the user can receive path guidance using the navigation device 10 through a minimum manipulation. For example, when path setting information is one, the user may receive a guide of a desired path with only a selection operation about whether to receive the path setting information. Even when a plurality of path setting information exists, the user may receive a guide of a desired path with only one operation of selecting one of displayed title information. Thereby, manipulation convenience of the navigation device 10 can increase and accident dangerousness can be reduced due to a manipulation of the navigation device while driving.

Further, by the present invention, the user can easily plan a trip together with families or acquaintances at a home. For example, the user can efficiently select a tourist site (a destination point and a passing point) by connecting to the data server 70 having various data using an IPTV or a PC at a home and specifically plan a trip by searching for a path to the tourist site and performing trial driving thereof. Further, by registering/inputting various additional interest information (historical archaeological sites, good taste restaurants, recommendation travel sites, etc.) around the found path as the user input information, when actually traveling, additional interest information can be provided through the navigation device and thus a boring moving time to a destination point can be usefully used.

Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and modifications of the basic inventive concepts herein described, which may appear to those skilled in the art, will still fall within the spirit and scope of the exemplary embodiments of the present invention as defined in the appended claims.
